Use of Fish Freshness Meter (Torrymeter) to assess quality of Malaysian Fish

Title	Use of Torrymeter to assess quality of Malaysian Fish

Fish Species	Kembong (Rastrelliger kanagurta), Gelama (Johnius pseudociama soldado), Parang (Chirocennus dorab), Tongkoi (Kishinoella tonggol; Euthynnus alleteratus), Merah (Wstipomoides typus), Kerisi bali (Prisfipomoides typus), Lidah or sebelah (Cynoglossus lingua), Sardine or tamban sisek (Surdinella fimbriata)

What the research is about

The paper gives a background to the various methods of quality evaluation that have been used in Malaysia. These methods are compared with the Torrymeter and some positive correlations were found between organoleptic assessment and Torrymeter readings. The Torrymeter was found to be more sensitive than visual scoring when the fish were relatively fresh and un-iced. The Torrymeter should find a wide use within the fish marketing system in Malaysia.

Research conclusion

Although different fish respond differently to the Torrymeter, a pattern can be formed for the majority of species. The most important criterion in this case is that it is a quick reference method to establish freshness for the layman, fisherman, fishmonger and research worker. More surveys would have to be carried out to establish norms for each variety of Malaysian fish.
